  • Publication number: 20110177258
    Abstract: A method and device disclose how to drain a liquid coating metal from the two sides of a running steel strip. The method transfers a strip coated with a liquid coating metal, as it runs at the tank outlet, from a region not subjected to a magnetic field to another region subjected to a static magnetic field generated between the poles of magnetic members arranged opposite each other on either side of the strip and having field lines, or at least a main shell of the field lines, intersecting with the strip over at least one minimum longitudinal extent so that the liquid coating metal is correlatively subjected to a magnetic field variation generating on the liquid metal a force opposite to the running direction. Due to the low field variation, this magnetic braking effect generates little Foucault current in the strip.

  • Patent number: 7799270
    Abstract: Electromagnetic device for fusion and interfacial agitation of diphase systems, particularly for the acceleration of metallurgic or pyrochemical processes, which includes for example a crucible to contain a diphase system, an inductor surrounding this crucible, and a circuit for the supply of the inductor by a current with two components, namely a high frequency component which melts the phases of the system and a low frequency component which agitates the interface of the phases.

  • Publication number: 20050200442
    Abstract: Electromagnetic device for fusion and interfacial agitation of diphase systems, particularly for the acceleration of metallurgic or pyrochemical processes. This device comprises for example a crucible (2, 28), to contain a diphase system, an inductor (4) surrounding this crucible and means (18) for the supply of the inductor by a current with two components, namely a high frequency component which melts the phases of the system and a low frequency component which agitates the interface (12) of the phases.
